Huzzah! The suspension has been rebuilt, and the headlight repaired and bolted on:
I've swapped out the bushes on the rebuilt side with normal rubber ones, and have done the top wishbone on the passenger side. I would have done the lower ones as well, but I managed to butcher several bushes trying to get them in. They kept sticking half way, and no amount of lubrication would get them to shift.
In the end I swapped the eyes on the arms out for the old ones from the other side that survived the crash. I assume the existing ones must have had some rough patches or something that I couldn't see that was increasing the friction.
I've also redone the camber settings on both sides using my phone as a camber gauge (works really well, btw). Now set to -1 deg on each side whilst under load.
Not done the tracking yet, but that should be a doodle when it comes to it. No worries about the rods falling out, and the nut on the extension is a great way of turning the rod to wind the upright in for positive or negative toe.
Almost ready for the body work to turn up!
